iMist helps FPA laboratory gain UKAS accreditation and undertakes testing into additional system purposes

iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression systems, has labored with main trade physique the Fire Protection Association (FPA), to help it acquire UKAS accreditation for certainly one of its fire-testing laboratory amenities – changing into the primary and solely check facility in the UK to hold this accreditation.
The fast-growing Hull-headquartered enterprise, which has developed its personal vary of high-pressure water-mist fire-suppression systems, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fireplace testing in Blockley, Gloucestershire, which is among the most comprehensive hearth take a look at and research operations in the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the assist of iMist’s skilled staff.
The UKAS accreditation of the FPA’s BS 8458 Annex C fire testing marks one other important milestone in the improvement of water-mist methods in the UK.
Alex Pollard, operations director of iMist, feedback: ‘For over 75 years, the FPA has been on the forefront of fireplace security and we’re proud to have assisted them in attaining this revered third-party accreditation. It is a further demonstration of the rising significance of high-pressure water-mist methods in tackling the present challenges facing the fire-suppression sector. เกจวัดแรงดัน do they use considerably less water than conventional sprinkler methods, they’re additionally easier and quicker to put in and, thereby, more economical.’

As a half of its ongoing R&D product testing programme, iMist has also undertaken a sequence of stay hearth testing at the FPA’s UKAS accredited laboratory, which has increased the system’s purposes, demonstrating that along with being put in in the cavity above the ceiling, the iMist system pipework can safely and successfully be installed under a plasterboard ceiling.
For the live fireplace tests, the iMist nozzle was fed by each flexible and solid pipework working beneath a regular plasterboard ceiling. In every of the tests, the gasoline load was ignited and the heat from the fire triggered the bulb within the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fine water-mist particles at excessive stress for half-hour. During this time, the temperatures at predetermined heights within the test cell were measured by thermocouples. At no level during any of the tests were any of the Annex C temperature limits breached and all the fires were efficiently suppressed.
Timothy Andrews, iMist business improvement director, added: ‘While fireplace system pipework is normally installed within the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent issues across the potential break-up of asbestos hidden in ceiling supplies. Our newest indicative tests present that the housing industry can now explore one other much less disruptive and extremely efficient possibility by putting in a water-mist system below the present ceiling. Given the growing must retrospectively match fire-suppression systems in order to meet the most recent regulatory requirements and bring older housing inventory up to present standards, that is nice information for both landlords and builders.’
